  • 컴퓨터의 정상적인 활동을 방해하는 공격행위는 네트워크로 연결된 컴퓨터를 기반으로 하는 사회 활동이 증가함에 따라 심각한 문제를 유발하고 있다. 하지만 기존의 네트워크 및 시스템공격에 대한 분류기법은 주로 공격자 입장에서 연구되어서 피해를 입은 시스템이 사용하기에는 부족하였다. 그래서 피해시스템 입장에서 공격을 정확히 분류하고 탐지할 수 있는 분류기법을 개발하는 것은 중요하다. 본 논문에서는 기존의 공격 분류방식을 분석하여 문제점을 발견한 후, 공격 분류방식이 가져야할 요구사항을 도출한다. 공격 분류기법의 요구사항을 만족하면서, 피해 시스템의 관리자가 공격에 대한 대책수립에 도움이 되는 공격 분류기법을 제안한다. 제안하는 분류기법은 공격방식에 따라 확장이 가능하므로 복합적 공격을 보다 정확하게 분류할 수 있다.

  • The purpose of this study is to verify the causal relationship between depression and aggressiveness among adolescents. The 4-year longitudinal data collected from 2,670 4th grade elementary school students by the Korean Youth Panel study was used in this study. From the analysis result using the Autoregressive Cross-Lagged Model, the depression and aggressiveness in adolescents were continued from elementary school 4th grade to middle school 7th grade in significant stability. In addition, the previous aggressiveness turned out to have significant positive effect on the later period depression. Similarly, the previous depression had significant effect on the later aggressiveness, but the direction was negative. This means that the adolescents's depression increases as their aggressiveness increases, but as the depression increases, the later aggressiveness of the adolescents decreases. There were no differences between girls and boys within the relationship of these two variables. Finally, the implication derived from the results, the limitation of this study, and suggestion for following studies were presented.

  • Aggressive fibromatosis is a rare soft tissue tumor with locally invasive and infiltrative characteristics. The mechanism of this invasive nature was not reported until now. Mutations or reduction of PTEN, tumor suppressor gene, in cancer tissues, have been found to be associated with invasiveness and metastatic properties of cancer cells. To know the pattern of expression of PTEN in aggressive fibromatosis, we analysed the expression of PTEN with immunohistochemical stain and immunoblotting. PTEN was homogeneously expressed in the normal musculoaponeurotic tissues, but absent or very faint in tissues of patients with aggressive fibromatosis as evidenced by western blot analysis and immunohistochemical examinations. Although the meaning of decreased PTEN expression in aggressive fibromatosis is not certain, it might be involved in the growth of the aggressive fibromatosis, and associated with phenotype of aggressive fibromatosis.

  • The purpose of this study was to explore the mediating effect of emotional dysregulation on the relationship between the specific domains of self-esteem and aggression. Three questionnaire were administered to 287 individuals and the multiple regression analyses and Baron and Kenny's hierarchical regression analyses were used. The result shows that social and objective ability and positive character had significant influence on aggression, while impulse control difficulties, lack of emotional clarity and limited access to emotion regulation strategies largely contributed to aggression. Moreover, emotional dysregulation functioned as a significant mediator variable for explaining the link between self-esteem and aggression. Impulse control difficulties have fully mediated positive personality and hostility, limited access to emotion regulation has partially mediated social and objective ability and hostility, respectively.

  • The purpose of this study was to verify the effects of verbal-violence prevention program on friendship and aggression of 2nd graders in elementary schools. In order to verify these purpose, total of 24 2nd graders from each different two elementary school located in the A-Gun(a rural-mountainous area) of JeollaBukdo. Out of students, 12 students were into the experimental group, while the rest of 12 students were into the control-group. Then, the experimental group participated in the verbal-violence prevention program. Both groups were pretested the questionnaire on friendship and the questionnaire on aggression. For 12 students of the experimental group, total of 10 sessions: (40 minutes per session and 2 times a week) of program were conducted. After the sessions were complete, students of two groups took the post-test for proving the effects of the program. The results through this study can be summarized as follows. First, there was a significant difference in friendship between the experimental groups which participated in the verbal-violence prevention program and the controlled group which didn't participate in any program. Second, there was a significant difference in aggression reduction between the experimental groups which participated in verbal-violence prevention program and the controlled group which didn't participate in any program.

  • The objective of this study was to the effects of depression, anxiety and stress on the aggression among depressed adults. Subjects are 91 depressed adults in D city. The structured and self-reported questionnaires were administered to subjects and IBM SPSS 21.1 program were performed for data analysis. All of aggression and depression(r=.62, p<.001), aggression and anxiety(r=.58, p<.001), aggression and stress(r=.62, p<.001) showed positive correlation. Depression affects the aggression that is significant explanatory variables(42.3%). The findings suggested that depressed adult's aggression for managing psychological management programs with interventions seem to be necessary.

  • The purpose of this study is to examine the mediating effects of aggression in the relationship between parental conflict and peer relations among adolescents. Data from 482 middle school students of Seoul by self-reported questionnaires are analyzed for the study. The results of this study reveal that there are gender differences in aggression and peer relation of adolescents. For both male and female adolescents, parental conflict is positively related to aggression. Aggression is negatively associated with peer relations of adolescents. Parental conflict and peer relations of adolescents are negatively related. The results from regression analysis indicate that aggression mediates the relationship between parental conflict and peer relations for male and female adolescents. This results suggest the need to consider family experiences and emotional states for understanding of peer relationships in adolescents.

  • This study was carried out to determine the relation between cognition, depression and aggression in the elderly. A questionnaire survey was conducted with 198 elderly people in K region. The results were as follows. (1) The cognition of the elderly showed significant difference by gender, age, religion, marital status, education, living together, healthcare and monthly income (p<.05), and depression showed significant difference by gender and monthly income (p<.05). (2) Cognition and aggression(r=.15, p=.030), depression and aggression(r=.39, p<.001) there was a significant correlation between. Physical aggression and verbal aggression proved most significant correlation among the sub-factors(r=.55, p<.001). (3) Depression (${\beta}=0.568$, p<.001) had an significant influence on aggression. The explanation power was shown to be 10.0%. Accordingly, aggression management programs that are tailored according to the depression level of the elderly are required, and nursing based on this consideration would be of help to improve their quality of life.

  • 무선 센서 네트워크는 개방된 환경에 단거리 무선 통신으로 정보를 수집하는 센서 노드와 이를 수집하는 베이스 스테이션으로 운영된다. 이러한 센서 네트워크의 특징으로 인해 공격자를 통해 쉽게 훼손될 수 있으며 대표적인 공격방법으로 싱크홀 공격이 있다. LEAP은 싱크홀 공격에 대응하기 위해 네 종류의 키를 사용하여 노드 간 인증을 하도록 제안되었다. 이 기법은 보안성을 유지하기 위해 주기적으로 베이스 스테이션까지의 경로를 갱신한다. 본 논문에서는, 내부 싱크홀 공격을 LEAP과 같은 키의 인증을 통하여 탐지하는 기법을 제안한다. 제안 기법은 이전 노드, 다음 노드와의 키 인증을 통해 공격을 탐지한다. 공격이 탐지되면 해당 노드를 네트워크에서 제외하고 경로를 갱신하며 갱신된 경로를 통해 새로운 키를 배포한다. 그러므로 제안 기법은 이전 노드, 다음 노드와의 키 인증을 통해 싱크홀 공격을 탐지함으로써 전체 네트워크 보안성 향상을 목적으로 한다.
